One of the PlayStation launch games which is a direct port of Total Eclipse from the 3D0. This game would not have looked out of place if it had been developed for the Mega-CD.
The game is pretty much a rail shooter which is always propelling you forward. You can slow down and speedup, but never stop. Controls are very sensitive making it impossible for precise aiming so it ends up as spray and pray and enemies die before you do.
Each world is split up into 4 rounds and end with a boss battle. The levels consist of two zones namely surface and tunnels. On the surface you can also do a roll manoeuvre but I didn't notice anywhere in the game where it is ever needed, although it can boost score while shooting upside down. Towards the end of the game the levels get long and some tunnels can lead to dead ends causing instant death! Also some tunnel entrances take you back to earlier parts of the level so some memorisation is involved here.
After the game is completed a Crystals Dynamics promotional video is shown at the end of the video. It couldn't be any more 90's era advertising if it tried ;)
